BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction and civil engineering field, and more particularly, to a bracket installation structure for supporting a formwork of a girder.

The girder bridge means a bridge structure composed of main girders arranged in the construction and civil engineering fields, and alternate and piers are formed, the girders are mounted thereon, and then the girder bridge is installed on the upper surface of the girder And the concrete is laid to form a bottom plate for supporting a person or a moving means.

In this case, in order to place and remove the concrete from the bottom plate of the girder bridges, it is necessary to install and remove the formwork on the girders. For this purpose, the worker always relies on the auxiliary scaffolding at a high position, It takes a lot of time and cost to install and dismantle the formwork, resulting in a problem of lengthening of the air.

Further, according to the conventional Korean Registered Patent No. 10-1101209 (entitled "Cantilever Portion of Bridge Slab Using Precast Permanent Support and Its Construction Method / Registered on December 26, 2011), the bottom plate or the formwork is permanently supported However, since the precast permanent base is made of concrete, the precast permanent pedestal has a considerable amount of self weight, which makes it difficult to carry and construct the precast permanent base. In order to fix the precast permanent base to the side of the girder, There still remains a problem in which complicated and dangerous work is required to pass the separate joining member back to the side surface (see Fig. 1).

Accordingly, there is a demand for a bracket mounting structure that is relatively light in weight and easy to install, yet still satisfies the structural stability, while permanently supporting the cantilever portion of the girder.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a support bracket installation structure that can be easily installed on a girder, can be semi-permanently used as needed or can be dismantled later, The purpose of this paper is to provide
